We played with FlexConnect for a number of months but still could not get what 
we needed it to do on a consistent basis. Essentially we wanted FlexConnect to 
drop users into their building VLAN so they would be able to easily interact 
with the same devices that the wired connections in the buildings could see. As 
I'm sure you know, this also resolves many of the Apple, Chromecast, etc., 
problems.

We did have one caveat though that we just couldn't get past -- we wanted to 
drop faculty/staff into one VLAN and students into another (we can easily 
return the proper VLAN for a particular client in a particular building from 
Radius server - FreeRadius with a call to our LDAP server for info) but  we 
also need to send everything else back to the controller for central switching 
(e.g., police connections, special bar-code scanners that roam and serve to 
identify a user, but not being used for client traffic, for example, to give 
out free flu shots to eligible folks or let folks into a sporting event). We 
just couldn't get past having 95+% locally switched and the remainder centrally 
switched for over 200 buildings many with now over 100 APs each without using 
FlecConnect groups which are limited to numbers way too small for our campus.

We can even live comfortably without roaming between buildings. MOst folks are 
not used to being able to roam between buildings downtown or many cannot roam 
between apartments off campus.

How did you get around the FlexConnect group problem?

I tested FlexConnect on 8.0.110.0. Here are my observations:

*Great alternative to switch data locally (obviously)
*No AVC Support
*When controller is down, AP goes into standalone more. Must make sure that AP 
is not able to reach any other controller you don’t want. This was fixed with 
an ACL.
*Client details page does not show client IPv6 address. Client still gets IPv6 
address. (PRIME does show it if you run a report).
*Client details page does not show VLAN ID.
*Putting AP in FlexConnect mode does not require reboot (Cool!)
*No IPv6 ACL support

More testing to do, but so far so good.

We use Cisco’s wireless solution with WiSM2s and a variety of WAPs. We actually 
implemented the guest anchor controller solution last year with dual 
controllers (WLC2504) and we’ve been happy.

I like Britton’s idea of using FlexConnect at the dorms to switch the student 
data locally. However, I believe there are some limitations that would keep us 
from using it such as no support for AVC, and some limitations on IPv6.

Hector,

You do not say what wireless solution you are using. Let me assume a Cisco or 
Aruba controller based solution. You can have vlans from your controller tunnel 
to an anchor controller in a DMZ.  Use 802.1X authentication based on AD groups.

This solution permits controlled internal access and, if you desire, unfiltered 
Internet access. Until recently, we did something similar with our open Guest 
wireless network on our Aruba system. We now use a different solution for this.

The anchor controller idea was based on Cisco wireless training several years 
ago. At that time, it was their recommended guest solution.

Subject: ResHall Wireless

I’m wondering how many of you treat the wireless in the ResHalls differently 
from the wireless on the rest of your campus. In terms of geography, we have 21 
ResHalls that are in the perimeter of our campus. Some of these buildings are 
next to academic or administrative buildings. Eduroam is our main SSID. So, for 
the longest time it has only made sense to broadcast eduroam everywhere. Now, 
on the wired side of the house, our ResHalls have a dedicated connection that 
gives them direct, non-firewall access to the internet (for access to campus 
resources, a student must VPN). This came about as a request from the students 
to have more freedom in their residence. Makes sense. But wireless is different 
as it goes through our campus core, traverses our perimeter firewall, and goes 
out our main internet connection.

I’ve struggled to find an alternative solution to this. We recognize that 
students in ResHalls are different in the sense that they pay for a place to 
live and should get an internet service that is similar to their home service. 
However, any alternatives that we have considered (separate SSID, dynamic VLAN 
assignment, user groups) just seem to complicate the setup.

Any good ideas out there or creative ways in which you have tackled this 
challenge?

Thanks,
